regulator: s2mps11: drop redundant sanity checks in s2mpg10_of_parse_cb()

The sanity checks being removed in this commit are useless as earlier
code already checks for all conditions, including all error cases like
out-of-bounds conditions. In other words, the code being removed here
has no effect, as any potential error it could catch will already have
been caught by earlier code.

The checks removed here are also incomplete (as they're off-by-one) -
they should have been checking >= ARRAY_SIZE() to be complete.

Simply remove this redundant and incorrect code.

No functional change.
